The present invention relates to the production of anti non functional P2X7 receptor monoclonal antibodies from hybridoma cell lines.

Pharmaceutical compositions and methods are described comprising at least one Y2 receptor-binding peptide, such as peptide YY(PYY), Neuropeptide Y (NPY) or Pancreatic Peptide (PP) and one or more mucosal delivery-enhancing agents for enhanced nasal mucosal delivery of the peptide YY, for treating a variety of diseases and conditions in mammalian subjects, including obesity.

The invention relates to purinergic (P2X) receptors, more specifically to P2X7 receptors, the generation of antibodies and the use of antibodies and immunogens that are capable of selectively binding to a non ATP-binding P2X7 receptor but not to an ATP-binding P2X7 receptor, for the detection and treatment of disease conditions, especially cancer.

Methods and compositions for the downregulation of P2X7 receptor expression or activity are disclosed. Preferred compositions comprise siNA. The methods and compositions are useful in the treatment of diseases characterised by increased 112X7 receptor activity, such as neuronal degeneration, Alzheimer's disease, inflammatory diseases, and some cancers.

The invention relates to an antigen binding site for binding to a P2X7 receptor, the antigen binding site being defined by general formula 1:FR1-CDR1-FR2-CDR2-FR3-CDR3-FR4

The invention relates to purinergic receptors, to antibodies and related fragments thereof for binding to said receptors, to production of said antibodies and fragments and to use of said antibodies and fragments for cancer detection and therapy. In particular the antibodies described bind specifically to non-functional P2X7 receptors expressed by live cells.

One aspect of this disclosure relates generally to lipid compounds that exert diverse effects in the endocannabinoid system, such as regulating CB1 and CB2 receptor or moderating other bio-macromolecules within the endocannabinoid system. Some of the compounds showed improved receptor binding affinity, and / or improved receptor subtype selectivity, and improved bio-stability. Some of the compounds exhibit activities to regulate the enzymes that moderate the bio-disposal of endogenous cannabinoids, such as the fatty acid amide hydrolase (FAAH). Some of the compounds exhibit activities to inhibit the anandamide transporter. Other aspects of the invention are pharmaceutical preparations employing these ligands and methods of administering therapeutically effective amounts of the preparations to provide a physiological effect.

The invention relates to producing humoral response to P2X7 receptors in individuals having cancer, and to minimizing the progression of cancer in said individuals.

Y4 receptor agonist peptide selected from the group consisting of: [Ala30]PP2-36, [Thr30]PP2-36, [Asn30]PP2-36, [Gln30]PP2-36, [Glu10]PP2-36, [Glu10,Leu17,Thr30]PP2-36, [Nle17,Nle30]PP2-36, [Glu10,Nle17,Nle30]PP2-36, their PP1-36 equivalents, and analogues and derivatives thereof as described in the specification, are selective agonists of the Y4 receptor relative to the Y1 and Y2 receptors, and are useful in the treatment, for example, of obesity and overweight, and conditions in which these are considered contributory factors, and in the treatment of diarrhoea and intestinal hypersecretion.

The present invention concerns compounds comprising, within short sequences from a specific regions of the 7TM receptor, that can modulate 7TM receptor-associated signal. The present invention further concerns methods for stimulation angiogenesis by administration of peptides derived from the EDG3 7TM-receptor.

Provided is a method of treating or preventing age-related macular degeneration (AMD) in a patient subject to, or symptomatic of the disease, wherein the method comprises restoring normal lysosomal pH (pHL), or acidifying an abnormally elevated pHL, thus decreasing or preventing a damaging accumulation of lipofuscin or waste products in the retinal pigment epithelium (RPE) cells of the eye of the patient. Further, this method is achieved by modulating the action of the P2X7 and / or P2Y12 receptors of the RPE cells, specifically decreasing the acidity (pHL) of the RPE lysosomes by administering selected receptor antagonists affecting the action of the P2X7 and / or P2Y12 receptors of the RPE. Methods for selecting and quantifying the effectiveness of drugs to restore pHL and determine outer segment clearance rates is also provided using a high through-put screening protocol.

The present invention relates to biological materials against P2X7 and more in particular to polypeptides, nucleic acids encoding such polypeptides; to methods for preparing such polypeptides; to host cells expressing or capable of expressing such polypeptides; to compositions and in particular to pharmaceutical compositions that comprise such polypeptides, for prophylactic, therapeutic or diagnostic purposes. In particular, the biological materials of the present invention inhibit the biological activity of the P2X7 receptor, such as activation by ATP.

The present invention provides polynucleotides encoding mutated PYR / PYL receptor polypeptides that are agonized by chemicals, such as bromoxynil, chloroxynil, ioxynil, coumatetralyl, dichlobenil, fenhexamid, benoxacor, and BTH, that do not agonize wild-type PYR / PYL receptor polypeptides, and expression cassettes and plants comprising the polynucleotides. Particular embodiments of the invention provide polynucleotides encoding mutated PYR / PYL receptor polypeptides having a mutation in the ligand-binding pocket of the PYR / PYL receptor polypeptide.
